: I am characterizing suspensions with ultrasound methods and I am searching for information
: material about system models for what happens with sound in suspensions.
: I am also searching for firms, materials or possibilities to get suspensions with known parameters
: like concentration, viscosity and particle size.
: If you can help me, please contact me.

The Ultrasonics and Digital Signal Processing Laboratory based at Nottingham University (formerly based
at Keele University) could probably help you. Their move to Nottingham is recent so have a look at their
old web site on http://udsplab.elec.keele.ac.uk. They use a number of different theoretical models for
particlate systems with both liquid and solid phases. The formulations include thermal losses and multiple
scattering effects. They have also a number of contacts with suppliers of formulations
for experimental work and a have done a lot of work developing ultrasonic spectromters for characterisation of
emulsions and colloidal systems in general.

The research groups address is:

UDSP Laboratory
Department of Electronic and
Electrical Engineering,
Nottingham University.
University Park
Nottingham
NG7 2RD
UK

The head of the research group is Professor Richard Challis who can be contacted
on +44 (0)115 951 5599
